### execute_circuit() error in Amazon Braket backend
A clear and concise description of the bug.
The Amazon Braket backend's execute_circuit() lacked parameter binding
logic. When circuits contained parameterized rotation gates, execution would
fail, making it inconsistent with Qiskit and Cirq backends.
Fix:
Added parameter value checking and processing
Used string keys in inputs dict (as required by Braket API)
Properly bind parameters to circuits
### Steps to Reproduce
1. run #612
### Expected Behavior
```
What should have happened?
parameter_values = backend_config.get("parameter_values", {})
if parameter_values and circuit.parameters:
# Braket accepts parameter names as strings in inputs dict
inputs = {
param_name: value
for param_name, value in parameter_values.items()
if param_name in {p.name for p in circuit.parameters}
}
task = backend.run(circuit, shots=shots, inputs=inputs)
```
### Actual Behavior
What actually happened?
` task = backend.run(circuit, shots=shots)
`
### Screenshots or Logs
Add screenshots or log output if applicable.
### Environment
- **OS:** e.g., Windows, Linux
- **Browser/Tool Version:** e.g., Chrome 96, Python 3.8
### Additional Context
